I'm offering this advice: First I get the impression your using a Canon camera, since you mentioned a Canon lens. Second, when your autofocus isn't working, have you noticed if the aperture value in the display is showing 00? The camera has sensors for autofocus, but it's not the same as the sensor to record the image. You shouldn't have to clean that sensor unless your getting fuzzy grey spots in your images. That is a sign of dust on the imaging sensor. If you get the 00 display for your aperture when the autofocus isn't working, its a problem of the camera communicating with the lens. The fix is simple, when you take the lens off the camera, you will notice a row of pins on the camera mount, and small squares on the lens mount. These are the contacts where the camera and lens communicate. Both should be gold in color. Use a pencil eraser, and clean the contacts. Just be careful not to get the "shavings" from the eraser into the camera or lens. After "erasing" the contacts, blow the shavings away. The put the lens back on the camera to see if the autofocus works, and to make sure the aperture value is showing a number other than 00. Dirty contacts can keep the camera and lens from communicating, causing these problems. I hope this solution helps. Also, if your not using Canon, the solution should be the same. Since I use Canon I'm more familiar with them. Daryl Hi, I bookmarked your site some time ago, I think the work you do is amazing!
